The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for Jaconé. We’ve got a 16-day window, and it’s a bit of a mixed bag, but there are some definite windows of clean waves to keep an eye on.
The water is sitting at 72°, which is basically bang on average for this time of year – nothing unusual there.
The surf kicks off on Saturday the 18th, but it’s pretty small. We’re looking at consistent 3ft waves from the East, with a short period of 7 seconds. The wind is a light cross-offshore from the East at 6 mph, which will keep things clean. The combined energy is weak (237). It’s surfable, but it’s not going to blow your mind.
Sunday the 19th morning is where it gets interesting. The wind goes glassy offshore from the NE at 6 mph, and the swell is a touch bigger at 4ft from the East, still with a short 8-second period. The energy is moderate (289). This is a good time to get a few clean ones.
Monday the 20th morning sees a bump in size to 6ft from the ENE, with a short 7-second period. The wind is a light cross-off from the NNE at 6 mph. The energy is strong (417). This is getting a bit bigger, but still manageable for intermediates. The afternoon drops back down in size.
We then have a few days of smaller, ordinary surf until Tuesday the 22nd afternoon, when we get another pulse of 5ft from the ENE with moderate energy (358) and clean cross-off winds.
The real standout, and the best on offer in the whole period, looks like Friday the 31st of July morning. You’ve got a clean 6ft swell from the ENE, a solid 8-second period, and light offshore wind from the NE at 6 mph. The combined energy is a very strong 470. This is the biggest, cleanest, and most energetic swell we see. It’s pushing 6ft, so it’ll be a bit much for beginners, but for intermediates and up, that’s a proper session. The crowds are listed as "sometimes," so you might have a few others out, but it’s not going to be a zoo.
The next morning, Saturday the 1st of August, is a write-off. A 12 mph cross-onshore wind from the West will ruin the 5ft ENE swell.
The very end of the forecast, on Sunday the 2nd of August afternoon, has a 3ft S swell with a long 13-second period, and the energy is very strong (648). The wind is a light cross-shore from the SSE. This is a long-period groundswell, which can be a bit tricky at a beach break like Jaconé – it might break too straight. Worth a look, but it’s a long way out and less certain.
Overall, the best bet is the morning of Friday the 31st of July. Get on it.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
